Security Policy Based on Firewall and Intrusion Detection System

Hemdeep Kaur Bimbraw; O. P. Gupta

Firewalls are usually the first component of network security. They separate networks in different security levels by utilizing network access control policies. The major function of the firewall is to protect the private network from non-legitimate traffic. The main purpose of a firewall system is to control access to or from a protected network. It implements a network access policy by forcing connections to pass through the firewall, where they can be examined and evaluated. Intrusion detection is the process of monitoring and searching networks of computers and systems for security policy violations. Intrusion Detection Systems (IDSs) are software or hardware products that automate this monitoring and analysis process. An IDS inspects all inbound and outbound network activity, system logs and events, and identifies suspicious patterns or events that may indicate a network or system attack from someone attempting to break into or compromise a system. The network security in today’s world is a major concern because of increasing threats from malicious users. Therefore, designing a correct network security policy is a challenging task. To design filtering rules to formulate a sound firewall security policy and implement intrusion detection system to capture network packets and detect attacks to fulfill this gap.
